 Stanley J309 300 Amp Jump StarterDec 29, 2009
By mavsimpson
Awesome! Plenty of jump start power. Purchased 1 from Amazon & another from my local hardware store(same model). Used 4 times in the last few days on our fleet vehicles. Cars/trucks/vans...no problems. Charging is easy on this model, just plug it in with an ordinary household AC extension cord or use the DC adapter supplied. Also, this unit has an on/off switch. My old one didn't so the terminals were 'HOT' all the time. Life saver device, well worth the bucks!

Works greatJul 18, 2010
By James
I bought this jumper to jump my motorcycle. The battery goes dead every winter and I am not in an area where I would be able to keep the battery charged over the winter (I am forced to park the thing out on the street). Anyway, this jumper works great - I plugged it in, let it charge for a day (although I don't think it requires a full day to charge) and jumped my bike right up - the battery on my bike was completely dead prior to the jump. Very easy, no problems.

Great productAug 31, 2011
By ashtong63
My battery wouldn't hold a charge and I used this every day for 4 months to start my car and it exceeded my expectations. I never expected it to last that long, but with charging once every 3 weeks or so it worked fine. Small, portable, and much easier than jumper cables. Highly recommended.

Best Price on AmazonJun 20, 2011
By Ralph M
I shopped eBay and major retailers, and Amazon had the lowest price for this item. I had previously read online reviews of similar products and decided that Stanley offered the best, along with a trusted brand name.
Shopping at Amazon is so easy, I do it often.

Works great for my purposesJul 02, 2011
By B. Chang
I use it to start my lawn mower and cars if necessary. So far, it has been working well. It is much better off for me to have this battery pack than buying a dedicated battery for my lawn mower. A great product!
